Razvoj zagonskega nalagalnika prek USB vodila za mikrokrmilnik serije STM32F4

TREBUŠAK, ALJAŽ (author), Jankovec, Marko (mentor)

V magistrskem delu smo predstavili rešitev zapletenega nalaganja vgrajene programske opreme na proizvodno orodje FVT. Razvili smo zagonski nalagalnik, ki omogoča nalaganje brez uporabe posebnih orodij. Obstoječ zagonski nalagalnik smo nadgradili, tako da omogoča preprostejše nalaganje vgrajene programske opreme z osebnega računalnika prek USB vodila. Pri tem smo morali upoštevati predpisan komunikacijski protokol. K obstoječi funkcionalnosti zagonskega nalagalnika smo dodali možnost obdelave in zapisa prejetih podatkov v programski pomnilnik orodja. Obenem smo nadgradili tudi obstoječi grafični vmesnik, ki zdaj omogoča nalaganje datoteke vgrajene programske opreme z osebnega računalnika. Program zagonskega nalagalnika je zasnovan modularno, kar omogoča uporabo v drugih proizvodnih orodjih in pri prihodnjih projektih. Proces nalaganja vgrajene programske opreme na orodje FVT smo avtomatizirali in poenostavili, kar bo pripomoglo k hitrejšemu razvoju orodij in s tem optimiziralo proizvodnjo izdelkov.

• Title: Development of bootloader via USB for STM32F4 series microcontroller

Abstract

In the master's thesis, we presented a solution to the complex loading of firmware on the FVT production tool. We have developed a bootloader that allows the loading without any special tools. We upgraded the existing bootloader to make the firmware download process simpler. The firmware is transferred from a personal computer to the FVT tool via a USB bus. In doing so, we had to follow the prescribed communication protocol. To the existing functionality of the bootloader, we added the ability to process and write the received data in the flash memory of the tool. At the same time, we upgraded the existing graphical user interface, which now allows us to download the firmware file from a personal computer. The bootloader's programme design is modular, which allows its usage in other production tools and future projects. We have automated and simplified the process of loading firmware on the FVT tool, which will help speed up tool development and thus optimise the production process.
